bug #39794: warnings when building avrdude 6.0rc1 under CentOS 6.4 

* buspirate.c: Turn the "cmd" argument of the various methods into
a "const unsigned char *"; while doing this, declare all arrays being
passed as arguments to be pointers rather than arrays, as the latter
obfuscates the way arrays are being passed to a callee in C.
